Hurricane Force Winds, Thunderstorms Slam West Central Montana

UPDATE: 7/25/24 7:45 AM 

More than 10,000 customers remain without power this morning, following the Thursday evening storm. Outages are scattered through Missoula, west to Alberton and east to Clinton, as well as the Northern Bitterroot.

Missoula Water is asking its customers to conserve water because they're having to use generators to power their pumps, with "limited ability" to refuel. Much of the system has been impacted by the storm and loss of power.

Original story 

The Missoula area, the Bitterroot Valley, and other areas of West Central Montana were slammed by severe thunderstorms Wednesday evening, downing lines and trees and starting fires.

The National Weather Service had been tracking the storm for several hours as the cells began moving across Idaho.

Around 8:30 pm NWS issued a warning of severe thunderstorms moving into the Northern Bitterroot and Missoula Valley, and when the weather came it hit hard, with pounding winds, lots of lightning, and heavy rain.

Additionally, forecasters tell us they reported a gusting hitting 109 miles per hour at the top of Mount Sentinel.

The winds ripped through Lolo and Miller Creek, knocking down trees and power lines. Then the storm blasted across Missoula and moved into East Missoula, kicking up a major dust storm and debris.

Lightning strikes were expected to total several hundred in the Missoula area.

Damage everywhere

Missoula area fire and police crews were kept busy responding to a rapid-fire succession of reports of downed power lines and trees, with multiple wildfire starts. At one point, firefighters were called out to stop a structure fire in East Missoula that was threatening other homes.

Missoula Electric Coop was reporting several hundred people without power from Lolo to Missoula to Superior and in Seeley Lake.

Northwestern Energy was also reporting several thousand customers without power in the Missoula and Bitterroot service areas.

Storm moved NE

The storm was continuing to move northeast toward the Upper Blackfoot, the Front, and Great Falls area before 10 pm.
